I compared the iPhone Ultra's rumored screen sizes to the Samsung Galaxy Z Fold 8: which of these foldables would you rather buy?

Both the iPhone Ultra and the Samsung Galaxy Z Fold 8 are foldable smartphones with unique form factors. The Galaxy Z Fold 8 features a passport-like design with a 7.6-inch unfolded display and a 5.5-inch cover screen. In contrast, the iPhone Ultra, rumored to be in the market soon, is expected to have a slightly larger 7.7-7.8-inch unfolded display and a 5.49-inch cover display. Both devices are likely to have AMOLED screens and similar brightness levels.

The key differences between the two phones lie in their dimensions and internal components. The Galaxy Z Fold 8 has a folded thickness of 9.0-9.6mm and unfolded dimensions of 120.6 x 167.6 x 4.5-4.8mm, while the iPhone Ultra's thickness and unfolded dimensions are expected to be slightly different. In terms of internal components, both phones are rumored to use similar AMOLED screens and have a similar aspect ratio, with the Galaxy Z Fold 8 having a 16:10 aspect ratio and the iPhone Ultra likely matching it.

Ultimately, the iPhone Ultra and the Samsung Galaxy Z Fold 8 may have similar foldable screens in terms of size and aspect ratio, with the iPhone Ultra potentially being slightly larger. Their cover displays are also expected to be very similar, with the iPhone Ultra possibly being slightly smaller. The main differences between the two phones will likely be their overall dimensions and internal components, with the iPhone Ultra potentially featuring more curvy corners.
